He hasn't yet. Sheamus is still WWE Champion.
Right now Sheamus has the championship, but I think John Cena is going to beat him but I think they want to to get the fans excited then win the championship back.
John Cena Will Win The WWE Championship At The Royal Rumble But Will Lose It To Sheamus At WWE Elimination Chamber.
Sheamus did beat John Cena at TLC 2009 for the WWE Championship. Which was Sheamus's first reign with the title, until losing it at the 2010 Elimination Chamber ppv to John Cena. Where McMahon screwed Cena, putting Cena in a match with Batista, after his original match and losed the title to Batista.
No. Cena is the world heavyweight champion right now and Sheamus is out injured. Sheamus is expected to be back only in early 2014, so I dont think a Cena vs Sheamus match for the WWE Championship is possible this year
Sheamus
no he lost to sheamus in a tables match for the wwe championship
I could guess after WWE Wrestlemania XXVI 2010, when Sheamus possibly loses it.
both
Yes john cena will win his wwe championship at noc and the champ will be back
John Cena defeated Randy Orton, Triple H, Ted DiBiase, Kofi Kingston and Sheamus to win the WWE Championship in the Elimination Chamber in 2010.
Every body knows that answer! John Cena!
John Cena via DQ.
